[Open Assets] Enemies Drop Rings 1.3.1

Hello, everyone. If you thought I've forgotten about this addon, then let me tell you that I didn't.

Anyways, this update addresses an issue with the object state check for Big Floating Mines and Detons. In the previous version, I used numbers instead of constants in the script to point to the states where the enemies would explode. This was a bad idea, because as new SRB2 versions arrive, some object states might get added or removed, making those numbers point to different states rather than the intended ones.

So what this update does is to replace those numbers in its script to the state constants that point to both enemies' explosions. This should hopefully make it future-proof.

Hello!
I edited the script so that enemies won't drop rings in Ultimate Mode, since it's meant to not have any rings.
This update might be pointless, but I felt like I needed to fix that.

Fixed a bug where Detons wouldn't spawn a ring if they exploded by crashing into a player.

Hello!
So, I fixed a bug where Big Floating Mines wouldn't spawn a ring only when a player causes them to explode (either by being too close or by touching it).
